Quoted from PanzerFreak:I don't see this happening, just my opinion, as Metallica offers a far better world under glass experience then Iron Maiden. Metallica has the large Sparky toy, the mechanical hammer with ball lock, the snake, and the moving cross.
Obviously, this is subjective BUT not a chance. I got to play Iron Maiden this week for 60 minutes. The world under glass aspect of Iron Maiden is better that Metallica. Met is great but Maiden has soooo much more going on under the glass and the overall art and theme integration is far better. Just my opinion over course.
